FLOOR CONSTRUCTION.

Application filed December at Chicago, in the county of Cook and State of Illinois, have invented certainnew and useful Improvements in Floor Constructions, of which the following is a specification.

This invention relates to a fire-proof floor construction in which tile blocks and con crete beams are arranged between suitable supporting beams.

It is my object to construct a floor wherein the beams support between them an arch that is formed of a plurality of tile blocks, each similar tothe others; a floor wherein the tiles composing each arch are arranged in rows that are reinforced by concrete beams at desired intervals; a floor wherein a skew of concrete is arranged between the end tiles and the beam proximate thereto; and a floor wherein are carried soifet tiles beneath each beam. the supporting means therefor serving also to prevent concrete from entering the cells of the adjacent end tiles.

()therobjects and purposes of this invention, as will more clearly hereinafter appear, are also in contemplation.

In the accompanying drawings is sho svn an exemplification of my invention in the manner followin Figure 1 is a horizontal section through a portion of floor taken approximately on line 11 of Fig. 2;

Fig. 2 is a transverse section thereof taken approximately on line 2-2 of Fig. l; and

Fig. 3 is a similar view taken on line 8-3 of Fig. 2.

In the construction of the present floor use is made of steel I-beams A set apart at desired intervals to support between them an S arch which, according to this. invention, consists of tiles B arranged in rows B, B B etc, with concrete C in the form of beams C, G etc, arranged preferably between each two rows of tiles, as best shown in Fig. 1. Upon the arch thus constructed may be arranged the usual filler tiles D (whenever the depth of the I-beams would require this) supporting a layer E of concrete wherein are set strips F to which the floor boards G are fastened.

The arc-h formed in the manner just described comprises a number of rows of tiles each of which is in the form of a rectangular block of standard construct1on. The sev- Specification of Letters 'Eatent. fartg tgd Aug, 29, 1922,

eral tiles in the arch shown numbered individually s a and, as is usual, may be hell t interior cells 10 (see Fig. 3). the arranged rows are suitably adhereo gether as at 11 by .eneans of moi-ti". and by preference these tile rows arranged in groups'of two with a concrete beam C, C etc, intervening. The end tiles which are simi ar L0 the others abut a skew ll of concrete which fills in the space between the lower flange 11 and web 1520f the i-beain and the proximate face ofthe end tile block 5 or 9, as the case may be. This concrete skew, as appears best in Fig. l, is united with each concrete beam C, C etc, so as to entirely surround the tile rows both on their ends and sides. The pouring of the concrete in this manner is facilitated by the use ofsmall channel tiles I, each facing up" ward, one tile being provided for h crete beam, so that the resulting cei i present an all tile surface. A desirable reinforcement for each concrete beam is at forded by the use of a rod or wire J which ma if desired lie within the channel tile, 7 J

cover the ends of some or all of the cells 10,

the concrete may be prevented from entering into the end tiles.

It will be observed that the construction herein described makes use of rows of tile blocks each of which may be of the same general shape so as to form an arch extending between a pair of Lbeams. Throughout the length of each row the several tiles present their ends squarely against each other, while the ends of each row abutthe skew of concrete, thus providing an arch which is capable of opposing end thrusts such as result from the imposition of a load thereupon. By a construction such as this, I dispense with the use of specially formed tiles such as keys, skews, etc, using instead only rectangular blocks oft-he kind that are commonly designed for partitions. This, of

course, is a great advantage both in regard to cost of material and expense of inst-allatiou. It is further of advantage to employ a greater number tile rows than concrete beams, this being rendered possible by forming the concrete beams integral with the skew so that the one derives reinforcement "from the other. In this manner a consider able saving is effected in the cost of material, and time of Construction, as well as in the weight of the floor.

I claim:

l. A liloor construction wherein is combined spaced I-beams, an arch extending between each two I bea-ms, each arch consisting of a transversely arranged concrete beam below which is a channel tile, in asso ciaticn with a row of tile blocks, each the same in. form as the others, the tile row being arranged transversely between the Ibeams in parallel and adjacent relation to the concrete beam, and a skew of concrete disposed bet-ween the end tiles of the row and the proximate I-beam, the ends of the concrete beam uniting with the skew, substantially as described.

2. A floor construction wherein is combined spaced I-beams arranged in parallelism, a longitudinally extending so'tfet tile beneath the lower flange of each I-beain, upwardly facing channel tiles arranged transversely between the soffet tiles at desired intervals, a rod aligned with each channel tile and having its ends adjacent the web of the I-beam, and over each channel tile a beam of concrete which also is extended adjacent the I-beams to form a skew, means for supporting each soffet tile consisting of an element engaged therewith and extending into the concrete skew, and tile arches between the I-beams arranged adjacent the several concrete beams, substantially as described.

3. A floor construction wherein is com ii-d spaced I-beams arranged in parallela longitudinally extending soflet tile beneath the lower flange of each I-beam, upwardly facing channel tiles arranged transversely between the soffet tiles at desired intervals, and over each channel tile a beam of concrete which also is extended adjacent the I-beams to form a skew, means for supporting each soffet tile consisting of an element engaged therewith and extending into the concrete skew, and tile arches between the Lbeams arranged adjacent the several concrete beams, substantially as described.

4. A floor construction wherein is combined spaced I-beanis between which is extended a tile arch with its ends abutting a skew of concrete which lies adjacent each beam, the tile arch being composed of a number of tiles arranged in double rows, and a concrete beam intervening between each two rows of tile and having its ends united with the skew, soilet tiles arranged below the I-beams as well as below the concrete beam in flush relation with the under side of the tile arch, the soffets being suspended from concrete forming the skew and beam, substantially as described.

5. A lioor construction wherein is combined spaced supporting beams on the opposite sides of which are formed concrete skews, an arch extended transversely between the beams and composed of a plurality of tile blocks having cells there-in arranged longitudinally of the arch, sofiet tiles carried below the supporting beams, and means supporting the soil'et tiles extending into the concrete skew and over the open end of the cells ofthe adjacent tile blocks, said means serving to prevent entrance of the concrete thereinto, substantially as described.
